Historical Asset and Strategy Performance During Inflation Surges

Summary

This review summarizes historical evidence on how assets and active strategies performed during periods of high and rising inflation in the United States, United Kingdom, and Japan. It defines inflation episodes using accelerating year-over-year inflation that reaches a high threshold, and also examines relationships between asset returns and unexpected inflation. The analysis spans a long historical sample and compares financial assets, commodities, real estate, collectibles, equity factors, and time-series trend strategies.

The main findings are that nominal bonds and broad equities often had weak real returns during inflation surges, while diversified commodity exposure performed comparatively well. Trend strategies on futures and forwards also showed strong results in the identified episodes; equity momentum was promising, though its estimates were less robust. The review discusses mechanisms such as rising discount rates and input costs, and reports historical return comparisons rather than a predictive model. Episode definitions, short samples for some assets, implementation costs, changing markets, and limited liquidity in collectibles constrain how directly these findings can guide current portfolios.

Key ideas

• The review compares passive assets and active strategies across historical episodes of high and rising inflation.
• Longer-duration nominal bonds and broad equities generally had weak real returns in the studied inflation episodes.
• Commodities performed comparatively well, though inflation-hedging behavior varied across commodity groups.
• Time-series trend strategies on futures and forwards had strong historical results during inflation episodes.
• Equity momentum also performed well in the sample, but the review cautions that the result is sensitive to episode definitions and statistically uncertain.
